Model Independent $Z'$ Constraints at Future $e^+e^-$ Colliders}
摘要
Model independent constraints on the mass of extra neutral gauge bosons and their couplings to charged leptons are given for LEP~II and a 500\,GeV collider. Analytical exclusion limits are derived in the Born approximation. The limits obtained with radiative corrections are always worse than those calculated at the Born level. Polarized beams are only useful for degrees of polarization essentially larger than 50\%. Known discovery limits on extra bosons predicted by popular models are reproduced as special cases. The constraints are compared to those predicted by four fermion contact interactions.
